Sets environment variables based on Git repo status for the use in shell scripts such as prompts.

git-status-in-env.sh

Sets environment variables based on Git repo status for the use in shell scripts such as prompts. Using this method allows for decoupling of interpreting the output of git status from logic and formatting. The behavior is defined by the tests to improve reliability and predictability.

Usage

Source the script then call the set_git_status_vars function. An optional prefix can be provided as the first argument to avoid potentially collisions with other environment variables.

. git-status-in-env.sh

set_git_status_vars MY_PREFIX

echo "Git branch is $MY_PREFIX_BRANCH"

Validation

Testing is implemented using ShellSpec.

Test locally with defaults:

$ shellspec

Testing with other shell versions using Docker:

$ shellspec --docker docker.io/library/bash:4.4 --shell bash

$ shellspec --docker ghcr.io/zsh-users/zsh:4.3.11 --shell zsh
